Conductive and electrostatic atomic force microscopy (cAFM and EFM) are usedto investigate the electric conduction at nominally neutral domain walls inhexagonal manganites. The EFM measurements reveal a propensity of mobile chargecarriers to accumulate at the nominally neutral domain walls in ErMnO3, whichis corroborated by cAFM scans showing locally enhanced d.c. conductance. Ourfindings are explained based on established segregation enthalpy profiles foroxygen vacancies and interstitials, providing a microscopic model for previous,seemingly disconnected observations ranging from insulating to conductingdomain wall behavior. In addition, we observe variations in conductance betweendifferent nominally neutral walls that we attribute to deviations from theideal charge-neutral structure within the bulk, leading to a superposition ofextrinsic and intrinsic contributions. Our study clarifies the complextransport properties at nominally neutral domain walls in hexagonal manganitesand establishes new possibilities for tuning their electronic response based onoxidation conditions, opening the door for domain-wall based sensor technology.
